SASH HINGING HARDWARE Filed March 30, 1943 Patented Aug. 21, 1945 Peter H. Kuyper, Pella, Iowa, assigno'r'to' Rolscreen Company, Pella, Iowa, a corporationof Iowa Application Marsh 30, 1943, se"ria1 No. 481,118;

' l Claim. (0,1. le 166) My present invention relates to sash hinging hardware particularly adapted for a swinging sash in a window frame, such asthe kind shown in my copending application, Serial No. 463,338, filed October 26, 1942. I

An object of my invention is toprovide sash hinging hardware which is simple to manufacture comprising a pane (if-glass is, lower and upper rails?!) and 22 and a pair of stiles 24, is mounted in 'an opening of the windowuframe for movement toclosed oropen position relative to such opening. Suchan arrangement makes a relatively simple window structure for factories and low and install and which involves a minimum of parts the guides and thereby hold the sash in various adjusted positions.

More particularly, it is my object to provide sash hinging hardware including arms secured to opposite edges of the sash and having shoes and links connected therewith, opposite frame members of a window frame having guides to receive the shoes, the arms being bent so that the shoes initially assume a position spaced farther apart than the distance between the guides, so that.

when the sash is installed the shoes frictionally engage the guides.

With these and other objects in view, my invention consists in the construction, arrangement and combination of the various parts of my device whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claim and illustrated in the accompanying drawing, wherein:

Figure l is an inside elevation of a window with the sash hinging hardware embodying my present invention applied thereto, certain parts being broken away and others shown in section to illustrate the hardware in relation to the window frame and the sash;

, Figure 2 is a vertical sectional view on the line 2-2 of Figure 1, this figure being on an enlarged scale and parts being broken out to conserve space on the drawing;

Figure 3 is a similar enlarged sectional view on the line 3-3 of Figure 1, and

Figure 4 is an enlarged horizontal sectional view on the line 4-4 of Figure 1.

On the accompanying drawing, the window frame illustrated has a sill It], a pair of side jambs l2 and a head jamb M. This frame is designed to be mounted directly in a wall opening, and to have a pane of glass l6 glazed directly therein. A sash,

cost homes, as brought out in my copending application hereinbeforereferred to. v

My present invention has to'do with the hardware for supportingthe sash in the window opening for opening and closing movement. The top of the window opening is defined by a mullion 26 and the sill Ill and this mullion are provided with weather-seal flanges 28 and 30, respectively, which interfit with the rabbets 34 and 32 of the sash when it is closed as shown in Figure 2. The side jambs l2 are likewise provided with flanges 36 with which rabbets 3B interfit in the closed position, with the hardware interposed therebetween, as will hereinafter appear.

L My sash hinging hardware comprises in general four elements, to-wit, a channel-shaped guide 40, a shoe 42 to slide therein, an arm 44 for attachment to the sash and a link 46. Two of these units are provided, one for each side of the sash. The channel-shaped guide 40 is secured as by a series of spaced screws 48 to the side jambs l2 adjacent the flanges 36. The shoes 42 are likewise channel-shaped and flt in the guides 40,, as shown in Figure 4. The shoes in turn are pivoted as at 50 to the upper ends of the arms 44. The arms themselves are secured as by screws 52 to the stiles 24 of the sash. They are secured in a subrabbet 54 of the stiles, which sub-rabbets thereby Vides a snug interfitting between the sash, the window frame and the hardware without interfering with the operation of the hardwarewhen opening or closing the window.

The links 46 are pivoted at their upper ends as shown at 56 to the arms 44. At their lower ends, wood screws 58 extend through the links and into the side jambs I2. for pivoting the links to the window frame; Accordingly, as the lower edge of the sash is pushed toward the left from its position in Figure 2, it willcause the links 46 to swing out as to the position of Figure 3 and at the same time the-shoes 42 will slide downwardly in the channel-shaped guides 40.

To hold the window in any adjusted position, it

is desirable to have the shoes 42 frictionally engage in the guides 40. This is accomplished by bending the arms 44 outwardly at the point indicated as 60 in Figure 3, with the initial bending of such extent that when the sash is installed the shoes 42 will be frictionally engaged with the webs of the channels 40. This is done by simply having thebends 60 of such an angle that the shoes are initially spaced farther apart than the distance between the webs of the channels. In Figure 1, for instance, I have shown the left side of the window frame broken away and the ariii 44 in its initial position such that the shoe 42 isfarther from the center of the window than the guide-40. After installation, the arms are under tension because of being forced back to the position shown at the right side of Figure 1. Thus, I provide a simple means to produce the necessary friction for holding the window at any desired position of adjustment without complicating the hardware with additional coil springs or the like. At the same time, the hardware is designed so as to minimize strains on the sash itself; due to the shoes 42 and the links 46 being pivoted to the arms 44 instead of directly to the sash. This arrangement also insures proper spacing of the pivots 50 and 56.

Some changes may be made in the construe" tion and. arrangement of the parts of my device without departing from the real spirit and pur pose of my invention, and it is my intention to" having its two flanges also located in Said pair 61' cover by my claim any modified forms of structure or use or mechanical equivalents which may be reasonably included within its scope without sacrificing any of the advantages thereof.

I claim as my invention:

Sash hinging hardware comprising guides adapted to be attached longitudinally along opposite sides of awindow frame arms adapted to be attached to the adjacent edges of the sash, said arms being angle-shaped in cross-section, shoes pivoted to said arms at one end and links pivoted to said arms at the other end, said links being angle-shaped in cross-section, said shoes sliding along said guides and the other end of said links adapted to be pivoted to said sides of said window frame, the end portions of said arms to which- .on said window frame to cause the shoesto frictionally engage said guides during their sliding movement threalong, each side of said sash having a pair of rabbets, each of said'ar'rhs' liavin its two flanges located in said part or rabbets' and each of said links, when the sash is' closed, forming an extension of its respective arm and rabbets.
